After reading Creating Sparse Finite-Element Matrices in MATLAB
I downloaded sparse2.m form SuiteSparse .
But when I use
D = sparse2(i,j,s);
It shows error
Error using sparse2 (line 27)
sparse2 mexFunction not found
Where can 'sparse2 mexFunction' be founded?

Does this package come with C/C++ source code that you need to compile yourself?

It has some C files. Please have a look on the files it has.

Did you read the README.txt file and followed the instructions?
================================================================================
QUICK START FOR MATLAB USERS (Linux, Mac, or Windows): uncompress the
SuiteSparse.zip or SuiteSparse.tar.gz archive file (they contain the same
thing), then in the MATLAB Command Window, cd to the SuiteSparse directory and
type SuiteSparse_install. All packages will be compiled, and several demos
will be run. To run a (long!) exhaustive test, do SuiteSparse_test.
================================================================================
Was SuiteSparse_install successful? If not, which error messages did you get?

Does this mean, that you try to run the files inside the compressed "suitesparse-5.4.0.tar" folder? Please explain with details, what you are doing.
If I get the error message "Cannot open include file: 'regex.h': No such file or directory", I'd search for this file manually at first. Which compiler are you using?
